title: Comparative study on the effects of different growth factors on migration of bovine corneal endothelial cells during wound healing.
abstract: OBJECTIVE
  In a comparative study we investigated the effects of epidermal growth factor, acidic and basic fibroblast growth factor, transforming growth factor-beta1, and vascular endothelial growth factor on proliferation and migration of cultured bovine corneal endothelial cells during wound healing.
  
  
  METHODS
  Cell proliferation was determined by incorporation of 5-bromo-2'-deoxy-uridine and by cell counting. To investigate cell migration, we established a method to produce identically shaped cell-free areas in monolayers of cultured cells and documented the wound-healing process.
  
  
  RESULTS
  Concerning the five tested growth factors, only epidermal growth factor as well as basic and acidic fibroblast growth factor stimulated DNA synthesis, cell proliferation, and migration during wound healing. Vascular endothelial growth factor stimulated migration during wound healing without influencing DNA synthesis or cell proliferation.
  
  
  CONCLUSIONS
  Whereas epidermal growth factor and the basic and acidic forms of fibroblast growth factor enhance proliferation as well as migration during wound healing, vascular endothelial growth factor seems to be a stimulatory agent specific for corneal endothelial cell migration.
